Hellgren G. On the theory of monopulse radar

Goteborg: Elanders Borktryckeri Aktiebolag, 1960. - 196 p.This thesis includes the following two papers:
G. HELLGREN: On the principles and angular accuracy of monopulse
radar. SAAB Technical Notes, TN 42, March 1959.
G. HELLGREN: Some characteristics of two simple linear and stochastically time-varying control systems of interest in angle and range measurement and tracking by monopulse radar. SAAB Technical Notes, TN 47, May 1960.
The present thesis is of purely theoretical nature. It deals with
the principles of monopulse radar and discusses how angular measuring
accuracy is influenced by electrical imperfections of the
receiver circuits, receiver internal noise, target glint, and target echo
fading. The thesis does not claim to cover all aspects of monopulse
radar techniques but only to increase our knowledge in this wide
field.
In paper no. 1 of this thesis the general principles of one-dimensional
angle-measnring monopulse radar are first discussed.
In paper no. 2 a theoretical study is made of the effect of echo
signal fading upon target angle-measurement and tracking by monopulse
radar in the presence of internal receiver noise and target
glint.

This means that you can search and copy text from the document. Some early printed books are hard to OCR-process correctly and the text may contain errors, so one should always visually compare it with the images to determine what is correct.
